如何向Spring数据中的条件添加复数和条件

import org.springframework.data.jpa.domain.Specification;
import javax.persistence.criteria.CriteriaBuilder;
import javax.persistence.criteria.CriteriaQuery;
import javax.persistence.criteria.Predicate;
import javax.persistence.criteria.Root;

public class MySpecification implements Specification<MyEntity> {

    private String condition1;
    private String condition2;

    public MySpecification(String condition1, String condition2) {
        this.condition1 = condition1;
        this.condition2 = condition2;
    }

    @Override
    public Predicate toPredicate(Root<MyEntity> root, CriteriaQuery<?> query, CriteriaBuilder criteriaBuilder) {
        Predicate predicate = criteriaBuilder.conjunction(); // 使用and连接条件

        if (condition1 != null) {
            predicate = criteriaBuilder.and(predicate, criteriaBuilder.equal(root.get("field1"), condition1));
        }

        if (condition2 != null) {
            predicate = criteriaBuilder.and(predicate, criteriaBuilder.equal(root.get("field2"), condition2));
        }

        return predicate;
    }
}

@Repository
public interface MyEntityRepository extends JpaRepository<MyEntity, Long> {

    List<MyEntity> findAll(Specification<MyEntity> specification);
}

@Autowired
private MyEntityRepository myEntityRepository;

public List<MyEntity> findEntities() {
    MySpecification specification = new MySpecification("condition1", "condition2");
    return myEntityRepository.findAll(specification);
}
